How does SellerMetrics sync with Amazon Advertising Account?
SellerMetrics syncs with your Amazon advertising account via their api.
This sync is initiated when you first sign in via "Login with Amazon", this first sync grabs all of your last 60 days of data between all of your accounts. That is why it will take a while until your accounts are first connected with SellerMetrics.
On a daily basis, at around 1 am PST, we will grab daily data from the Amazon advertising api.
